Bet you thought I forgot about them D|.

Anyway, there's a collection of spirits that I have in mind that I like to call "twin spirits". They are there to balance each other out and if you find one the other is surely not too far behind.

I like to call these twins Positive and Negative. BET YOU CAN'T GUESS WHICH ONE IS WHICH LOL.

Their abilities are rather various, leaving people rather unprepared for whatever power the two decide to unleash upon them.
Negative: Despite the mischievous grin it's wearing right now, Negative is a pessimistic and a sadist. It can drain energy from almost anyone and anything and plants wither and fade whenever it draws near. When Negative feels like having a good time, it chooses a host and simply brings out the worst in them. Focusing on their faults and personal demons. Until Negative has had it's fun with you, it will not leave unless you have someone remove it for you. Or you can rely on sheer will power. Good luck with that.

Positive: Unlike it's twin, Positive is, of course, optimistic and would rather give energy than take it. It can give power to any device even it if has no batteries or isn't plugged in. To the dismay of Negative, Positive prefers to bring out the best of it's host, that is, if it ever chooses one. Positive is picky as it is shy and feels that it should only possess someone who truly needs it. When it comes to removing Positive the same method that is used for Negative applies, however, it does not take as much will power. If you ask nicely, Positive will leave you be.
